</li>
<li><p class="first">Use the mach header information to print the cpu type of a

<p>Changed the code because of issue #6, in which a user tries to
dump a iOS binary which results in bogus output in the previous
releases.</p>
</li>
<li><p class="first">The mapping <tt class="docutils literal"><span class="pre">macholib.macho_dump.ARCH_MAP</span></tt> is undocumented

definition and isn&#8217;t actually used in the codebase.</p>

<p>Bug fixes:</p>
<ul>
<li><p class="first">The semantics of <tt class="docutils literal"><span class="pre">dyld.dyld_default_search</span></tt> were changed a bit,
it now first searches the framework path (if appropriate) and then
the linker path, irrespective of the value of the <tt class="docutils literal"><span class="pre">DYLD_FALLBACK*</span></tt>

<p>Previous versions would change the search order when those variables
was set, which is odd and doesn&#8217;t correspond with the documented
behaviour of the system dyld.</p>
